I don't know IN the car off the top of my head but you can just cut one of the wires at the switch in the trunks back left hand side. I just unplug the harness back there to kill the pump if I want to work on the engine without turning the pump. That would be an easy bypass though if the would-be theif knew half way what they were doing. You can find that harness in the back and follow it forward to where it goes under the back seat and tap into the wires there. Install the rear seat again...hide your switch. SO if they tried to follow the harness to find the "break" they'd have to take the time to remove the back seat if they can't find your switch first. thats how I would do it.
